Biopsychology

Question 1

Answer 1

central nervous system and peripheral nervous system

Question 2

what is the central nervous system made up of?

Answer 2

bran and the spinal cord

Question 3

what is the peripheral nervous system made up of?

Answer 3

autonomic nervous system and somatic nervous system

Question 4

what is the autonomic nervous system made up of?

Answer 4

sympathetic nervous system and parasympathetic nervous system

Question 5

what are the four divisions of the brain?

Answer 5

-cerebrum
-cerebellum
-diencephalon
-brain stem

Question 6

how does the central nervous system work?

Answer 6

-The Spinal Cord relays information from the brain to the rest of the body
-In order to do this, it is connected to the different parts of our body by pairs of nerves
-In addition to relaying information, the Spinal Cord also has circuits of nerves that enable us to perform reflexes without any direct involvement from the brain

Question 7

what is the cerebrum?

Answer 7

the cerebrum is the largest part of the brain and is divided into four lobes, which each have their own primary function

Question 8

what are the four lobes that the cerebrum is made up of?

Answer 8

-frontal
-parietal
-occipital
-temporal

Question 9

what does the frontal lobe do?

Answer 9

functions such as thought speech and learning

Question 10

what does the parietal lobe do?

Answer 10

processes such as pain and touch

Question 11

what does the occipital lobe do?

Answer 11

visual information and memory

Question 12

what does the temporal lobe do?

Answer 12

hearing

Question 13

where is the cerebrum and where are all the different lobes located?

Answer 13

see paper flashcard

Question 14

what is the name of the part of our brain that connects the two hemispheres?

Answer 14

Corpus Callosum

Question 15

what is the cerebellum involved in?

Answer 15

the cerebellum is involved in a person’s fine motor skills and balance, helping to coordinate our muscles and allow precise movements

Question 16

if someone had abnormalities in their cerebellum what could it lead to?

Answer 16

-speech and motor problems
-epilepsy

Question 17

where is the cerebellum located?

Answer 17

see paper flashcard

Question 18

what are the parts of the diencephalon?

Answer 18

-thalamus
-hypothalamus

Question 19

what does the thalamus do?

Answer 19

acts as a relay station in our brain for nerve impulses by routing the impulse to the part of the brain that it’s relevant to

Question 20

what does the hypothalamus do?

Answer 20

it is the brain’s main link to a different system, called the endocrine system- as part of this, it helps to regulate our body temperature as well as our feelings of hunger and thirst

Question 21

where is the diencephalon located?

Answer 21

see paper flashcard

Question 22

what does the brain stem do?

Answer 22

The Brain Stem helps by regulating the automatic functions that are essential to keep us alive, such as breathing, digestion and heart rate

Question 23

why is the location of the brain stem relevant?

Answer 23

because of its location, motor and sensory neurons travel through the brain stem, connecting our brain to the spinal cord, and eventually the rest of our body

Question 24

where is the brain stem located?

Answer 24

see paper flashcard

Question 25

what does the periphery nervous system do?

Answer 25

All of the nerves that aren't part of the CNS are in the Peripheral Nervous System. It's job is to relay impulses to and from the CNS and the rest of our body.

Question 26

describe the makeup of the somatic nervous system and what it does

Answer 26

The Somatic Nervous System is made up of 12 pairs of Cranial nerves that emerge directly from the bottom of the brain, and 31 pairs of Spinal nerves that emerge from the spinal cord. Each of these pairs contains a sensory neuron and a motor neuron. As well as transmitting this information and the instructions of how to respond to it, the somatic nervous system is also involved in reflexive actions.

Question 27

how many cranial nerves are in the somatic nervous system?

Answer 27

12 pairs

Question 28

what are cranial nerves?

Answer 28

nerves that emerge directly from the bottom of the brain

Question 29

how many spinal nerves are there in the somatic nervous system?

Answer 29

31 pairs

Question 30

what are spinal nerves?

Answer 30

nerves that emerge from the spinal cord

Question 31

what does a sensory neuron do?

Answer 31

takes information to the CNS

Question 32

what does a motor neuron do?

Answer 32

takes information from CNS to the body

Question 33

what does the autonomic nervous system do?

Answer 33

-The ANS helps us to carry out bodily functions that work much better if we aren't thinking about them. These include: heart rate, breathing and digestion -it is also involved in the flight or fight response and is split into two further systems to allow us to have this response to emergencies

Question 34

what is the key neurotransmitter involved in the sympathetic nervous system?

Answer 34

noradrenaline

Question 35

what does noradrenaline do in the sympathetic nervous system?

Answer 35

-releases adrenaline -pupils dilate -increased heart rate -released stored energy -lungs expand -produce more sweat -digestion slows

Question 36

what is the key neurotransmitter involved in the parasympathetic nervous system?

Answer 36

acetylcholine

Question 37

what does acetylcholine do in the parasympathetic nervous system?

Answer 37

-stops the production of adrenaline -pupils constrict -decreased heart rate -stores energy -lungs contract -less sweat is produced -digestion continues as normal
